To all whom it may concern:

Be it known that we, WILBER O. PLATT and JOHN REID, both citizens of the United Internal-Combustion Engines, of which the following is a specification.

This invention relates to a device to be located within the combustion chamber of an internal combustion engine for the purpose of vaporizing and igniting the fuel, and particularly to that type of such deignite or both vaporize and ignite the fuel. spray, and are sufiiciently isolated from the cylinder Walls and piston, to enable them to take up and retain heat from the repeated combustions sufiicient to vaporize or ignite or both vaporize and ignite the fuel.

7 The object of the present invention is to provide a device of this kind which will be more economical. to produce, more effective in operation, more durable under the high temperatures to which it is subjected, and which will be more readily replaceable than devices heretofore constructed.

In carrying out the invention, we employ a vaporizing surface that is made up of a plurality of units in the form of bars, suspended at their ends with their intermediate portions exposed for action; these bars being preferably of cylindrical section, so that they can be constructed from stock material, they will not develop warping effect like plates used for similar purposes, they will afford a greater contact surface for a given area than a solid body or plate, and they are readily removed and replaced when impaired; moreover, they may be rotated in position to present diflerent portions of their surface to the fuel.

The invention will be fully understood upon reference to the accompanying drawing, in which- Figure 1 is a sectional view of a portion of the cylinder of an internal combustion engine with its contained piston; Figs. 2 and 3 are end views of the piston shown in Fig. 1, Fig. 3 having the vaporizer support to receive the multiple unit vaporizing and body removed; Fig. 4. is a side view of the vaporizer looking from right to left in Fig.

2, and Fig. 5 is a transverse section. on the line 55, Figs. 1 and 2. i

1 represents the piston working in the cylinder 2 ofan internal combustion engine, operatingupon the principle of having its fuel injected through a spray nozzle 3.

4 is the water jacketof the engine.

Located upon the end of the piston 1 are a pair of supporting lugs 5 spaced apart to receive the multiple unit vaporizing and igniting body made up of rods 6; said lugs being ofsufiicient dimensions to isolate the rods 6 from the piston 1, so that said rods can take up and retain heat of one explosion surliciently to ignite the fuel to produce the next explosion.

To mount the rods 6 on the lugs 5, the

the rods, but open at the other end to admit them; said grooves having at a suitable point intersecting bores 5 in which a long rod may be introduced and riveted as at 6 for the purpose of confining the rods against displacement. The rods 6 may be tubular, but they are preferably solid to increase their heat-storing capacity. They may be of any suitable material but a nickel alloy is preferred in order to reduce oxidation and distortion. They may be of any de sired section, but polygonal or circular section is preferred, as the heating surface attainable'with a given area is thereby increased and the impact faces are presented in better position for deflecting the sprayed fuel and thereby sub-dividing it and mixing it with the air that is to support combustion. When the multiple unit spraying surface becomes impaired, it is an easy matter to remove one of the ends 6 of the retaining rod and to remove said rod in order to release the others. The rods are preferably in lateral contact with each other, but they may also be sufficiently loose to be rotated to change the surface presented to the fuel sprayed upon them.

We claim 1. In an internal combustion engine, a vaporizer and igniter actin upon the fuel, comprising a plurality of individually detachable rods suspended at both ends in the combustion chamber; said rods accumulating suflicient heat from a previous explosion latter are provided, ontheir opposed faces,- with grooves 5 closed at one end to confine to vaporize and ignite the fuel for a subse quent explosion. I

2. In an internal combustion engine, a vaporizer and igniter acting upon the fuel, comprising a plurality of individually detachable .rods suspended at both ends in the combustion chamber; said rods accumulating sufficient heat from' a previous explosion to vaporize and ignite the fuel for a subsequent'explosion, and'mean s for suspending said rods, comprising lugs between Which said rods are secure 3. In an internal combustion engine, a vaporize-r and igniter acting upon the fuel, comprising a plurality of individually detachable rods suspended at both ends in the combustion chamber, said rods accumulating suflicient heat; from a previous explosion to vaporize andlignite the fuel for a subsequent explosion, and means for suspending said rods, comprising lugs having in their opposed faces, grooves receiving the ends of the rods.

4. In an internal combustion engine, a vaporizer and igniter acting upon the fuel, comprising a plurality of rods suspended in thecombustion chamber, and means for suspending said rods, comprising lugs having in their opposed faces, grooves receiving the ends of the rods; said grooves being open at one end to admit the rods.

5. In an internal combustion engine, a vaporizer and igniter acting upon the fuel, comprising a plurality of rods suspended in the combustion chamber, and means for suspending said rods, comprising lugs having in their opposed faces, grooves receiving the ends of the rods; said grooves being open at one end to admit the rods; said lugsbeing recessed transversely to and near one ;in the combustion chamber and adapted to accumulate sufiicient heat from a previous explosion to vaporize and ignite the fuel for a subsequent explosion, and. means for suspending said rods at both ends comprising lugs between which said rods are secured; said'lugs being located upon the end of the piston.

S. In an internal combustion engine, a piston, lugs projecting from said piston and spaced apart thereon, said lugs being provided With grooves in their opposed faces, rods secured between said lugs with their ends resting in said grooves, and a retaining rod extending through the lugs inter secting the grooves and having its ends enlarged to prevent displacement of the retaining rod.
